Hi everyone. With help from Ron E., I managed to make ATSC  
decoding work using the SDRPlay RSP.  
The big issue was that the RSP has a DC bar in the middle of the  
waterfall. Canceling it in the SDR program isn’t enough; you have to get  
the latest driver and use the EXTIO options _in addition_ to the  
Automatic DC cancellation in HDSDR.
